| Name | Alexander A |
| Experience Level | 1/5 |
| Remarks | It was very large compared to the planets and stars in the distance. The largest space object I have ever seen in the nighttime sky aside from the moon. Maybe 1/10 to 1/15 the size of a full moon. My eyes caught it immediately. Jade green fire. It was in front of, below, and to the right of the bright moon above the dark middle school baseball field. Gone in flash. |
